New Leupold 3-9x40mm UltimateSlam Slug Scope Atop New Savage 220 Slug Rifle
 

Hi,

New to the community, I am an avid hunter/shooter, but always eager to learn more and correct mistakes along the way.

I am having trouble sighting in the scope and slug-gun mentioned above in the title.

To summarize...I am hitting an inch high at 50 yards, right where I want to be. When I shoot at the 100 yard, I am about 8-9 inches high, holding dead-on the bullseye? Thats where I am messed-up on.

I am shooting Hornady SSTs, 250gr. Any help/input would be greatly appreciated.

Thank you.

do you have the booklet for it i just put one on my muzzleloader as well

The Savage 220f love the Remington Accutips 3", also what scope mounts are you using? I love the DNZ one piece, if your right hand use part # 18200......

with the above named ammo and scope mounts I'm shooting 4" at both 50 yds and 100 yds, dead center at 150 yds, 4" low at 200 yds, and my groups at all ranges are super tight

Yes, I have the booklet, box, the whole deal. Been reading over the booklet before the shoot, now after, haha. Mine is a shotgun slug application.

I have the scope on low profile Leupold rings on an EGW one peice picatinny base made for the 220. I am currently shooting the 2 3/4 250gr. SSTs. I do have 2 3/4 260gr. Accutips, I have just heard better performance with Accutips in general.

Going to start from scratch, 25 to 50 to 100, then 200.

Not sure why you are getting that odd trajectory.
I would dial it in where you want it at 100yds (dead on?, 1" high?) then see where it shoots at 50, 150, etc. and adjust from there.

If it was me, I'd be most concerned with dialing it in to your expected range. I'd bet that most shotgun slug shooters probably shoot under 125yds the majority of the time. If you expect most of your shots 150-200, sight in accordingly.
